Since before 2016 Elon Musk has told people his vehicle is ready to drive itself, and he very notoriously has told owners they can sleep at the wheel.
Musk estimated that by the middle of 2020, Tesla’s autonomous system will have improved to the point where drivers will not have to pay attention to the road. […] “A year from now, we’ll have over a million cars with full self-driving, software… everything.” These cars will be Level 5 autonomy with no geofence, which is a fancy way of saying they will be capable of driving themselves anywhere on the planet, under all possible conditions, with no limitations.

It has always been a dangerous lie.
A Pennsylvania man hit another driver, along with construction signage, while asleep behind the wheel of a self-driving Tesla. On Friday, April 11, around 4:20 p.m., an unnamed driver was traveling west on U.S. Route 22.
According to police, the driver was asleep at the wheel and using Tesla’s self-driving feature to navigate. While the car was self-driving, it hit the driver’s side of another vehicle before driving into a sign that was up to signify a construction zone.
Perhaps, most notably for Q1 sales numbers, Elon Musk said at the start of 2025 at CES that his software would eliminate all crashes this year.

Instead, Tesla vehicles in 2025 have continued crashing – side-swiping other cars, colliding with each other, running red lights, and hitting buses and trucks broadside.
